OpenSSL < 0.9.6j / 0.9.7b Multiple Vulnerabilities

According to its banner, the remote host is using a version of OpenSSL older than 0.9.6j or 0.9.7b. This version is vulnerable to a timing-based attack that could allow an attacker to guess the content of fixed data blocks and may eventually be able to guess the value of the private RSA key of th...

OpenSSL 0.9.7a and 0.9.6i released

From the changelog: Security fix: Vaudenay timing attack on CBC + In ssl3getrecord ssl/s3pkt.c, minimize information leaked + via timing by performing a MAC computation even if incorrrect + block cipher padding has been found. This is a countermeasure + against active attacks where the attacker h...

Vulnerability in OpenSSL CVE-2003-0078

sl3getrecord in s3pkt.c did not perform a MAC computation if an incorrect block cipher padding was used, causing an information leak timing discrepancy that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading...

Timing attack vector for remember me token

The current rememberme token verification process leaves the application open to a timing attack. Since the default is for the token to be stored as a cookie and for cookies to be encrypted, an attacker would have to know the application secret to exploit this. However, should a custom guard be...
